Patent CA-2256385-C (CA)
Inventor: MARTIN JOHN D
IPC: B01D35/153
Filed: 1997-05-23
Granted: 2005-12-06
Abstract: A radial-flow filter (120) employing nonbonded granular particles (56) for filtering impurities from an influent, and that can be backwashed by fluidizing the granular particles (56) to free the impurities therefrom. During a backwashing operation, a backwash liquid applies an upwardly-directed drag force on an upper portion of the granular particles (56) to lift the same into a backwash chamber (62) for fluidization. Once the top portion of the granular particles (56) of the filtration bed is fluidized, the backwash liquid applies an upward force on a subsequent portion of the granular bed, thereby fluidizing the granular particles (56) in the backwash chamber (62). Subsequent sections of the granular bed are fluidized in a similar manner to thereby completely clean the granular particles (56).  After the backwash operation, the granular particles (56) fall back to the filtration chamber (156) and form a filter bed for carrying out a filtration operation.

Abstract: An access point (GGSN) from a mobile communications system to an external system is selected (3) at a serving node (SGSN) of the mobile communications system based on at least two or three grounds of selection: the subscription data of a mobile subscriber stored in the mobile communication system or an access point selection data given by a user in a service request (1), or on other grounds. The serving node sends to the access point (GGSN) selected a further service request (4) which includes indication of the grounds of the selection, i.e. whether the access point is selected by subscription, by a user, or based on any other grounds. Thereby the access point is able to distinguish and accept service requests in which the rights of the user are already assured by the subscription, without any security problems. When the request is based on the selection of the access point by the user, or on any other insecure grounds, the access point is able to make any further actions to ensure the security. These further actions may include rejection of the service request.

Title: Panel testing apparatus and method
Inventor: LAU KENNETH K
IPC: G07D7/182
Filed: 2000-03-30
Granted: 2002-05-07
Abstract: Apparatus and method for non-destructively testing the stiffness of wood panels having opposed panel surfaces and ends. The apparatus comprises a support framework having infeed, centre and outfeed support assemblies mounted to the framework in spaced, successive positions. Each support assembly is adapted to contact the opposed panel surfaces of each panel to define a travel path along which the panel is advanced through the assembly. A first deflection member is provided intermediate the infeed and centre support assemblies and is movable to contact one of the panel surfaces as each panel extends between the infeed and the centre support assemblies with one end of the panel being supported by the infeed support assembly and the opposite end being supported by the centre support assembly. The first deflection member acts to bend the panel to a first pre-determined curvature.      In a similar manner, there is a second deflection member intermediate the centre and outfeed support assemblies movable to contact the same panel surface to bend the panel to a second pre-determined curvature. Load cells associated with the first and second deflection members measure the force require to bend the panels to the pre-determined curvatures for calculation of the stiffness of the panels. The infeed, centre and outfeed support assemblies are movable relative to each other to position the support assemblies such that the travel paths through the support assemblies define a generally "C" shaped path through the apparatus that accommodates the curvatures that each panel adopts in travelling through the apparatus. The apparatus provides a compact panel testing unit by virtue of the novel "C" shaped travel path through the apparatus that is able to operate at the high speeds of a production line.
